srowen commented on issue #25279: [SPARK-28519][SQL] Use StrictMath log, pow functions for platform independence URL: https://github.com/apache/spark/pull/25279#issuecomment-518917299 I did not benchmark this as I think it's a correctness issue that would be worth a perf hit. I also expect it makes almost no difference - computing a function in SQL is dominated by so much more than the math here. Let me assess that though with some microbenchmarks.
